Product Introduction:

Our tungsten carbide rotary burr set are engineered for unparalleled precision and efficiency in metalworking. Operating at an impressive speed range of 15,000 to 45,000 turns per minute (Turn/min), these rotary files exemplify high-performance craftsmanship. With a hardness rating (HRA) between 89 and 92.5, they offer exceptional durability, ensuring longevity even in demanding applications.

Parameter Information:

• Hardness (HRA): 89-92.5, indicative of superior wear resistance.
• Rotational Speed (Turn/min): Operates efficiently between 15,000 and 45,000 turns per minute.
• Cutting Precision: Achieves precise cuts, contributing to high-quality workpieces.

Type of Cut: Our Tungsten carbide rotary file set offer versatile cutting options, including:

1. Standard Double-Cut: Ideal for general-purpose material removal.
2. Fine Cut: Precision cutting for intricate detailing.
3. Fine Double-Cut: Combining finesse with efficiency for superior results.

1.Speed /RPM

The speed at which you use your carbide bur in your rotary tool will depend on the material you're using it on and the contour being produced but it's safe to say you do not need to exceed speeds of 35,000 RPM. The table below shows some approximate speeds.

2.Apply only a little pressure
As with all drill bits and burrs, let the burr do the work and apply only a little pressure otherwise the cutting edges of the flutes will chip away or become smooth too quickly, reducing the life of your burr.

3.Keep The Carbide Burr On The Move
When using your carbide burr try not to keep it still for too long as this will prevent the burr from digging and jabbing into your material causing unsightly marks and roughness.
